CVE-2026-28376: Vulnerability in Grafana Grafana OSS
The Grafana Live push endpoint can be exploited to cause unbounded memory allocation by sending a large or streaming request body, potentially leading to out-of-memory conditions. An authenticated user with access to the Grafana Live API can trigger this issue.
AI Analysis
Technical Summary
The Grafana Live push endpoint in Grafana OSS contains a vulnerability (CWE-770) that allows an authenticated user with access to the Grafana Live API to trigger unbounded memory allocation by sending a large or streaming request body. This can cause the system to exhaust memory resources, resulting in out-of-memory conditions and potential denial of service. The CVSS 3.1 base score is 6.5, reflecting a medium severity with network attack vector, low attack complexity, and requiring privileges but no user interaction. No vendor advisory or patch information is currently provided.
Potential Impact
An authenticated attacker with access to the Grafana Live API can cause the Grafana server to allocate excessive memory, potentially leading to out-of-memory conditions and denial of service. There is no indication of confidentiality or integrity impact. The impact is limited to availability disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the Grafana Live API to trusted users only and monitor resource usage to detect abnormal memory consumption.
